Anyone know the ins-n-outs? Looking on what commands to issue to modify headlight operations and turn DPF and EGR off. I have the hardware to do it..and can issue any commands..just don't know what commands to issue. Anyone?????
 
No...no ...no...I want to learn the commands to issue to make fogs come on with the high beams (commanding the TIPM) and turn the EGR and DPF off (commanding the WHF?) ....not one in the same. LOL
 
There is no reason why I can't issue the commands to change headlight/fog light function, door lock at speed, radio delay after key off, all that crap. H&S can do it and they only plug into the CAN-C Diag port (former ODBII). It has to be just commands issued over the bus. I just need to figure out what they are.

ANYONE?
 
Doubtful it anything that you can just send a signal on the CAN BUS, it is in the ECM software/program.
